I'm with Leia on this one. However, I'd stress--get the 'name brand' pipe EE cart. Many 'off' brands have drawbacks.
For me, the best of the lot is Frontier(I have heard that the CTM is much the same as a Frontier, but have no personal experience with it.) I have owned two Frontiers in 25 years; sold the first only because the seatback was beat-up from ponying a little stallion who liked to BITE it-it is not pretty, but is still going strong for the person who bought it from me! I never had a 'down' day with EITHER one; had to replace the wheel bearings in the second one, but Frontier carries them, and they don't cost much.
I had puncture-RESISTANT tubes, and 'goop', put into my Frontier's wheels at a bike shop, and have never had a flat while driving...even when I did a cross-country course out across native NM hills, cactus included.
No, they are NOT a show cart, or suitable for the rigors of a serious CDE marathon course, for the most part, but for an everyday-use, knockabout cart which will allow a passenger, is easy to get into and out of, and is LIGHTWEIGHT(Frontiers weigh @ 78 lbs., give or take), that is still quite reasonable in price, I think they are hard to beat! Be leery of 'homebuilts' and/or knockoffs, though---I've seen quite a few that were much heavier, and/or had other serious drawbacks.
I've owned several Jerald show carts, a genuine Meadowbrook,Pequea's 'top-of-their-line' wooden Road Cart,an IteBte, and a Bennington. All were/are quality vehicles, but as noted, they are a good bit more expensive, often a lot heavier in weight, and/or not really suitable for the breed show ring. I always 'come back' to my trusty Frontier for everyday driving of a single.
